Presentation transcript:

OBJ: Find the volume of rectangular and triangular prisms. Section 13.1 Part 1

What is volume? the amount of 3-dimensional space an object occupies AKA capacity. Cubic units

What is the difference between surface area and volume? Surface Area The area of all the outside surfaces of a 3d object Volume The space inside a 3d object

Rectangular Prism

Example: What are the volumes? 6 4 8

Triangular Prism Formulas: V = (area triangle base)(height) Or V = (½bh)(prism height) Steps: 1. Find the area of the triangular base. 2. Multiply the area of the base by the prism’s height. Base height Base (b)height (h) Height of prism

Example: What are the volumes?
